Šćepović scored his first professional goal on 4 September 2010, netting the last of a 2–0 home success against FK Hajduk Kula. On 29 October of the following year, after netting the second in a 3–1 win against FK Smederevo, he gestured with his finger on his lips to "hush" some spectators in the east tribune of Partizan Stadium which had provoked him during the match.[2] He also scored in Partizan's 2–0 win in the Eternal Derby against Red Star Belgrade on 26 November,[3] being also given the Man of the Match award by Serbian newspaper Sportal.[4]
Armband affair
On 6 August 2013, after captaining Partizan in a 0–1 UEFA Champions League home loss to Ludogorets Razgrad (1-3 aggregate loss), a Grobari leader named Miloš "Kimi" Radisavljević jumped down onto the pitch and removed the armband of Šćepović's arm.[5] On 7 August, the scandal became even more controversial when a media conference was held with Radisavljević and Šćepović, with the former claiming to the press that he did not "aggressively" take the armband, and that he and the latter were "friends".[6]
In spite of the bizarre media conference and Šćepović passively agreeing with Radisavljević in the conference, criminologist Zlatko Nikolić of Serbia's Criminal and Social Research Institute gave voice to a widespread public suspicion that the conference was staged and that Šćepović was humiliated and may have been threatened to agree with the latter in the conference.[7] Despite the Serbian Ministry of Internal Affairs promising to investigate the matter thoroughly, Radisavljević was released after a 90-minute interrogation by the police.[8] About the incident, Milutin Šoškić said, "We have imported hooliganism from England, but we don't have a Margaret Thatcher to neutralize it."[9]
Olympiacos
On 2 September 2013, Šćepović signed a four-year deal with Olympiacos, for a €3.5 million fee.[10] On 22 February 2014, he scored his first hat-trick in his career, in a 4–0 away win against OFI Crete.[11]
Despite scoring four goals for the Greek outfit, Šćepović only started in seven matches during the whole campaign, totalling 650 minutes of action.

On 20 August 2014, Šćepović was loaned to Spanish Segunda División side RCD Mallorca in a season-long deal.[12] An undisputed starter during the beginning of the campaign, he scored braces against CA Osasuna and CD Lugo.
Terek Grozny (loan)
On 25 February 2015, Šćepović joined FC Terek Grozny on loan for the remainder of the 2014–15 season.[13]
On 30 August 2016, Šćepović signed a three-year contract with Fehérvár.[15]
Later career
On 30 August 2019, Šćepović signed a three-year contract with Turkish Süper Lig club Çaykur Rizespor.[16] He subsequently played for Thai club Buriram United in 2020, and for Cypriot side Omonia during the 2021–22 season.
On 6 February 2023, after more than six months without a club, Šćepović signed a short-term deal with Lugo in the Spanish second division.[17]
